MACHINE FOR WINDING ARMATURES.

SPECIFCATION forming part of Letters Patent No. 350,828, dated October l2, 1886.

pplieaiion filed February El, 1F86. Serial No. 191.364. (No model.)

To all whom, it may concern:

Beitknown that l, Li'ouN BIGELOW JONES, of Bedford, in the county of Hillsborough and State ofNew Hampshire, have invented a cer- 5 tain new and useful Improved Machine for .Vinding Armatures and l do hereby declare that the followingisa full, clear, and exact description of the same.

This invention has reference to improveiii'eiitsin winding-machines, and is specially designed for winding the wire upon armatures for dynamo and magnetoelectric machines, electroiiiotors, andthe like, its object being to do this work morc efficiently and expeditioiisly than can be accomplished by hand.

The main points of my windingmachine. are an annular gear carrying the spool and necessary tension devices revolving upon an annular extension ofvilie bed plate or frame,

2@ and having a removable section to admitpart of the armaturerim to the interior ofthe annular gear, a ci rciilar platform or ring upon which the armature rests while being wound, capable of being rotated as the winding of the different bobbins proceeds,and means for moving said platform or ring, and the armature carried thereliydaterally, to insure the proper ceiling or laying of the wire.

For full comprehension, however, of my in- 3o vention, reference must beliad to the annexed drawings, in nhieh letters of reference similar to those used in the following detailed description indicate like parts.

lln said drawings,Fignre l represents a plan view of my windingmaehine, Fig. 2, a side view partly broken away, and Fig. ."5 an end view of same.

A is the bed-plate, cast to somewhat the shape shown, a c being curved arms or extensions 4o projecting vertically from the bed to afford an annular `iournal or ways for an annular gear or spur wheel, B, to revolve upon, the teeth of this gear being on the outer periphery and in mesh with a pinion, B, the shaft of which is journaled in the bed-plate and carries on its opposite end the driving-pulley D. This annular gear or spur wheel has a removable section, B2, which held in place' while the niachine working by countersunk studs b I), a

5o side plate,or other suitable means, and the entire wheel is held in place On the journal-arms a c by means of a tongue.aad-groove connection or other approved armiigement which will leave it free to revolve.

C is a spool, the spindle of which passesinto the side or flat portion of tlie spurwvheel B, upon this spool being wound sufiicient wire to complete one bobbin ofthe armature, andc c are tension-rollers, also journaled to the wheel B', over and between which the wire Z passes 60 from the spool to the armature, as seen bythe dotted line in Fig. 2.

Upon the bed-plate A are formedhorizontal ways uf a, in which slidesa table or frame,E, ot' suitable construction to carry on its top a 65 semi-ringshaped platform, F, of somewhat larger circumference, suitable curved or circular ways, ce', heilig provided to steady same, while permitting it to be also turned on its circular ways when reivluired, as will be hereinafter explained. Passing through this ring or platform F, or screwed therein, are two or more npwardly-projeeting pins,fj, upon which the armature (shown by dotted lines) will rest, suitable holes being made in saine to receive said pins, thus providing means for holding the armature firmly in posit-ion while the bobbins are being wound. (This arrangement of pins and holes may be only adapted to a special style of armature-corewsuch as one made SO up of a number of flat plates or rings bolted togetlierthe pins being arranged to match and fit into the bolt-holes 5 but I intend to iisc different holding devices to snit the various styles of armatures adapted to be wound on my machine.)

The platform F is not a complete ring,a segment of the circle being open to permit the spur-wheel B to enter in such manner that the ring-armature carried by the platform may 9o pass and be revolved Within theannular wheel. after the fashion of one chain-link within another, the wheel B revolving in. a vertical plane, and the platform and armature being rotated in a horizontal plane.

Ahorizontal screwed shaft, G, suitablyjournaled in the bed-plate A, is connected to the table or framev E, and by the rotation ol' this shaft said table or frame is caused to slide in the ways a (1..

which this screwed `shaft may be worked by hand, but l intend in some cases to connect I have shown a wheel, g, by roo same by proper gearing or other mechanical devices with the driving-shaft, so that the backand-forth motion may be given to the frame and platform automatically.

5 The operation of my invention is as follows: The section B2 of the annular gear B having been removed,the annular core of the armature to be wound is placed upon thesemi-ring-shaped platform F, with one part of its circumference [o Within the annulus ofthe gear, theopen part of the platform leaving part of the armaturecore free, so that a number of bobbins may be Wound consecutively without changing theposition of the core with relation to the platform.

The removable section B2 is then replaced and the core properly fastened on the platform. The spool (Milled with the'wire,being in place, and the free end having been passed through the tension devices, is taken down to the ar ma- 2c ture, as indicated in Fig. 2, and properly fastened in one of the bobbin-spaces, which will v be arranged in the proper line by shifting the platform F. Power is then applied to the driving-pulley, and the pinionB causes the annular spur-,wheel B to revolve. This mo- `tion draws upon the wire and winds it tightly upon the core, the spool C meanwhile unwinding, each complete revolution of the wheel B passing the wire once around the core. The 3o attendant, when the hand-wheel g is used, or the proper mechanism when the work is done automatically, will move the platform slowly in a lateral direction (by bringing the screwed shaft Gr into operation againstv the table or frame and causing it to slide in the Ways c ed) as the Winding proceeds, and thus lay the wire in even coils side by side. Vhen one bobbin p is finished, a fresh spool is putin place, and

the core is adjusted to bring another bobbinspace in line by turning the platform on its circular ways e c', and the operation is repeated. After all the bobbins which cover the open 1. A machine for Winding wire upon armature-cores,consisting of an annular spur-wheel carrying a spool and having part of its periphery removable, and a platform capable ofr being rotated in a plane at right angles to the plane of revolution of said spur-wheel, and means for revolving said spur-Wheel and moving said platform laterally, substantially as and for the purpose set forth.

2.. In a machine for winding 'wire upon armature-cores, the combination, with the bedplate A, having adriving-shaftj ournaled there in, curved arms or extensions a a,and ways a a, of annular gearB,having removable section B2, and carrying a spool and tension devices, table or frame E and platform F, movably attached thereto, and screwed shaft G, all substantially as and for the purpose specified.

3. In a machine for winding armatures, the combination, with the movable ring or platform F, of pins j", for holding the armature-y core thereon, substantially as described.
